For XPE spreadsheets, you can enter information for the I/Os involved in the interface between the Xilinx device and external memory by using the Memory Interface Configuration wizard. The Memory Interface Configuration wizard provides a simplified method of filling in the memory interface I/Os in the XPE spreadsheet.
When you configure a memory interface using the wizard, rows will be added to the I/O sheet for each output line (for example, Data, Address, and Clock) from the Xilinx device that will be applied to the external memory.
The Memory Interface Configuration wizard can be started from the I/O sheet by clicking the Add Memory Interface button.
For a description of the Memory Interface Configuration wizard and how you can run the wizard from the I/O sheet, see Using the Memory Interface Configuration Wizard.
To understand the 7 series memory interfaces and the settings you will enter within XPE refer to the Zynq-7000 SoC and 7 series Devices Memory Interface Solutions (UG586).
